Imaginarium Discovery Deluxe Marble Race 100 Pieces Gears Loops Waves Marbles and More

My three-year-old son loves this toy. We assembled it just as shown in the picture on the box, and not all the components are used when it's assembled that way, however I think that leaves room for a bit of creativity. My only concern which is reflected in my star rating, is that the plastic itself is not super flimsy but it's also not the best quality. Some of the pieces feel like they could easily come apart as they don't fit very snug however it serves its purpose and I think the price is fair. My son really loves it and that's really what matters.
